FZ6R V-Stacks (im thinking about group buy, How about you???)

[Marthy]

dude 5hp of my gains is from modding the ecu and adding an ignition advancer. The full exhaust, fuel controller, and airbox mod only gave me 17hp. Then add the ignition advancer for another 5+hp. You gotta find a way to get an advacer on that pig.

The ECU as been unlock already. It should get available within a month or two. It remove all speed limiter and throttle servo control and all those goodies including fuel and ign map. The days of piggyback controller are coming to an end! I'm trying to work a deal to get mine flash with a tune for my exhaust. That should be sick as F*&^!

That little EJK fuel controller that I used actually did an awesome job. Very easy to use and get the job done as good as a PCV. The unit as extra feature that... you can go crazy like locking the ride by wire WOT and cheat the speed limiter... nothing I need to worry about but it can be done.

AH, dyno schedule for Thursday! Apakrovic has an exhaust out. - 5 lbs and + 5 HP for about $1200-1500. The numbers are so bad that the link as been pull out I think. LOL Not sure how my numbers will end up but as a reference on the FZ8, that was good for +12HP and 6 ft.lb

Since I posted about the FZ6R, seems it got a interest in the flashing the ECU.
When you can get into the ECU and can do some tuning in it, it opens up a whole new experience.
Air, fuel, spark the 3 major components for a good running engine, playing with fuel only does little to what can truly be done, for example MAPing timing on a dyno yields good power improvements in all areas of the rpm range.

So here a few concepts I made in the meantime still have to go home and get accurate dimmensions and tweek it a little bit im sure... I have also got a few qoutes going...

Hey I've seen stacks like that before somewhere and not dealing with motorcycles, etc. I'll have to think on it but it looks like it would work depending on size. Maybe cars, computers, a vaccum.....I'll get back to you.

Maybe port tubes for sub boxes?

Yep, That might be what I'm thinking of. They are just a couple bucks and come in different lengths and size.
Just an example:

a link to where I can purchase??? and ill check against my model to see if what the inside diameter was my only prob with that picture is that I have to assume the top of the cone is 2" not the lower end. but I hate assuming.

Google: port tube subwoofer
You'll find plenty or roll by a local car install shop

Sorry to bump such an old thread but did you go anywhere with the new vstack Marthy? Not sure if you did it on the 6R or Z8


Ninja Edit: NVM, I found your other thread Marthy with the airbox mod. HA!

It was on the 6R. Worked very well and improve the mid to top end. The easy mod is to go with all 4 short stack. You can buy them cheap online. The aluminum one were quite expensive for not that much better IMO. Combine that with cutting the bottom of the airbox and you're good to go.

Just doing that alone won't give you much but if it's part of a whole exhaust/tune package you will notice the difference.

Hrmm, I shall continue on with more research on why factory decided to stagger the oem vstack. I am assuming its to balance out/generate mid range power and considering the header design is a 4-2-1 to generate low end power.

Any particular site or company that you would recommend for vstacks?

Would anyone know how much cfm our heads flow?

Just to improve the power back across the RPMs.Short stacks will improve top end a bit.

Another question in regarding the vstack that you used. Did you end up going with the tapered vstack or a straight stack? because now air velocity is ticking away in my head.

fluid dynamics...interesting stuff.

From my understanding of that thread. Nothing was really concluded. Even with the other guys that were doing the air box mod. They also never updated after their own encounters with issues or just getting the stacks on.

It feels nice to know that simple mods aren't so expensive. Unlike my car...stupid car haha.
